2 Claims.

This invention relates to an electrical connection and it aims toprovide a novel construction which will avoid tangling, undue-strainingand breaking of the wires, and more specifically aims to provide aconstruction in which the parts are swiveled together.

The more specific objects and advantages will become apparent from aconsideration of the description following taken in connection withaccompanying drawing illustrating an operative embodiment.

In said drawing:--

Figure 1 is a view of the connection in side elevation,

Figure 2'is a vertical sectional view on an enlarged scale taken on theplane of line 2-2 of Figure 1,

Figure 3 is an inverted plan view of the connection.

Figure 4 is a cross sectional view taken on the line 4-4 of Figure 2,and

Figure 5 is a cross section'taken on the line 55 of Figure 2.

Referring specifically to the drawing, a body or sectionlO of insulationhas a neck 11 which extends into and is swiveled in a second body ofsection 12 of insulation. Extending from the body 12 are metallicconductor prongs 13 and 14, respectively, preferably made in a singlepiece and having tangs 15 and 16 by means of which they are detachablybolted as at 1'7 and 18 to the body 12. Prong 13 at the inner end has aring 19 integral therewith and disposed at a right angle thereto. Afterthe prong 13 is secured in place, but before the prong 14 is mounted, aconductor sleeve 20 is secured to the neck 11 in any suitable manner,for instance, by friction, and the same has an annular flange at 21which underlaps the ring 19. Thus the body 10 carries the sleeve 20 andflange 21 constantly moved in contact with the ring 19. 'A conductorstrip 22 is formed as a tongue on sleeve 20 and secured in any suitablemanner as by means of screw 23 to the body 10. One of the feed wires forthe currentis shown at 25 and is fastened in place in contact with strip22 by means of the screw 23. The companion conductor is shown at 26 andis secured by a screw 2'7 in contact with a conductor 28 whichterminates centrally of the plug 10 in an enlargement 29 at the base ofan extension 30 of neck 11. The outer surface of the enlargement 29 ispreferably spherical. The prong 14 has an inward extension at- 31,preferably of less thickness than the remainder of the prong to alfordresilience, and which extension 31 is in constant wiping contact withthe enlargement 29. As a result the wires will not become twisted sincemovement of body 10 relative to body 12 maintains electrical contact 1:the flanges 19 and 21 and enlargement 29 and Various changes may be madeprovided they fall within the spirit and scope of the invention.

What is claimed is: 1. A connection of the class described comprising abody section, conducting elements se-. cured to the body section, one ofthe elements terminating in a ring, the other element having a resilientextension spaced outwardly of the ring, a section of insulation abuttingthe body section and having a neck extending thereinto, a conductingsleeve carried by said neck and having a flange underlapping said .ring,a conductor strip carried by the section of insulation in conductingrelation to said sleeve, a conductor member carried by the section ofinsulation extending through said neck and engageable by said resilientextension, and an extension on said neck, said conductor member having aspherical surface at the base of said extension directly'engageable bysaid resilient extension.

2. A connection of the class described comprising a body section,conductingelements secured to the body section, one of theelementsterminating in a ring, the other element having a resilientextension spaced outwardly of the ring, a section of insulation abuttingthe first mentioned section and having a neck extending thereinto, aconducting sleeve carried by said neck and having a flange underlappingsaid ring, a conductor strip carried by the section of insulation inconducting relation to said sleeve,

a conductor member carried by the section of insulation extendingthrough said neck and engageable by said resilient extension, anextension on said neck, said conductor member having a spherical surfaceat the base of said extension directly engageable by said resilientextension, and-an operating sleeve detachably secured to the firstmentioned section and enclosing the second mentioned section, saidsleeve having an outwardly extending flange adjacent its free end.
